3. INTRODUCTION
This project is mainly designed for elderly and disabled people. Home Automation is
popular as it helps in reducing efforts and errors because of human and it further
increases the efficiency. Different applications like lights, fans, TV, AC etc. Can be
controlled by use this project through Bluetooth wirelessly. Other types of Automation
Systems include Internet Controlled, RF Controlled or IR based Remote Controlled. Based
on the application requirement we can prefer the type as each has its own advantages
and disadvantages. In this project , by sending a Voice Command we can control where
different appliances. The main controlling component in the system is Arduino UNO,
whose working is explained in later section. The proposed system has mainly two parts,
they are
Voice recognition system, and (b) wireless data transfer system. In this project controlling
of home appliances are done by using a voice controlled android application. It is easy for
users to make use of remote access to control various applications.

4. HARDWARE DESCRIPTION
• Android Base Phone
• Bluetooth Module
• Arduino Uno
• Relay

5. ANDROID PHONE
• It Is only use for Bluetooth connection and receiveing voice
command.

6. BLUETOOTH MODULE
• Serial wireless data transmission can be achieved
by using this module. Its operating frequency is
2.4GHz.

7. ARDUINO UNO
• It is an open-source microcontroller. The Arduino/Genuino
Uno can communicate with computer, or other Arduino
boards.

8. RELAY
• A electromagnetic relay is made of a coil of wire wrapped around a soft iron core
(a solenoid), an iron yoke which provides a low reluctance path for magnetic flux,
a movable iron armature, and one or more sets of contacts (there are two
contacts in the relay pictured). The armature is linked to the yoke and
mechanically connected to one or more sets of moving contacts.

13. CONCLUSION
• In conclusion, generally speech or voice recognition interface can
be implemented in many applications. Home automation based
on voice recognition has been built and successfully developed in
this project. The voice recognition system in this project is
identified until 20 m of range to transmit the signal from the
smart phone to the home appliances via Bluetooth. This system
was targeted for elderly and disabled people. Voice system is a
sensitive system, so other disruption such as weather, buildings
and noise must be avoided to get a better performance.
